Engine coolant level drops over time; visible coolant under generator or in drip tray.

Safety: Allow engine to cool before inspecting; pressurized hot coolant can cause burns.

• Visual inspection: Trace all coolant hoses, radiator/heat exchanger, and water pump for wet spots, dried coolant residue, or drips.
• Tighten clamps: Gently tighten hose clamps on any seeping joints. Do not overtighten plastic fittings.
• Pressure test: Use a cooling system pressure tester to pressurize the system to cap rating and look for leaks.
• Replace failed components: Replace cracked hoses, leaking radiator cores, or a water pump with coolant weeping from the weep hole using Volvo Penta parts.
